Sending Email in an ASP.NET MVC 4 and C# application

Hi every body. I have the code below to sending email with my application:

Code:

using (var client = new SmtpClient("mail.kekely.com")) {
    client.Port = 25 // also I tried with 587;
    client.DeliveryMethod = SmtpDeliveryMethod.Network;
    client.EnableSsl = false;
    client.UseDefaultCredentials = false;
    client.Credentials = 
        new NetworkCredential("[email protected], "mypassword");

    try {
        client.Send(My_Message_Goes_Here);
    } catch (ArgumentNullException) {
        throw;
    } catch (ObjectDisposedException) {
        throw;
    } catch (InvalidOperationException) {
        throw;
    } catch (SmtpFailedRecipientsException) {
        throw;
    } catch (SmtpException) {
        // I get an SmtpException error
        throw;
    } catch (Exception) {
        throw;
    }
}

In my local computer it works with port = 587. But when I upload the app to the Winhost it does not work and I get a SmtpException error. I searched the forum and follow any suggestion I found about issues same as mine, but the problem still exists. Do you have any idea please?

 

No my have not a mail server somewhere else.
I have registered my domain on GoDaddy, but I don't know how to set my DNS records to Winhost specifics. Actually Winhost does not supplied full information about DNS records. I just set my @ records to access my host on Winhost.
